Notes:
Summary Adjacent corn and ryegrass plots were fertilized with rates of 0, 50, 100, 150, and 200 kg N as ammonium nitrate/ha. Corn growing on this soil did not respond to fertilizer N while ryegrass responded to rates of up to 200 kg N/ha. The differences in N availability was also reflected in the higher profile NO3−N under corn than under ryegrass. The same general trends occurred on a second soil, where N availability for the hay crop was also less than for corn crop. Compared with corn, hay responded more to N fertilizer and had lower soil NO3−N levels. Grasslands appear to respond to higher N fertilizer rates than cultivated crops on the same soil.
